About the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL40X150SCA
The B52-MBL40X150SCA is AirTAC's copper-free (copper-prohibited) version of the MBL40X150SCA, a compact double-acting aluminum mini round cylinder. With a 40mm bore, it delivers 628 N push and 528 N pull at 0.5 MPa, and 880 N push at 0.7 MPa. The 150mm stroke suits short-travel positioning tasks in machines where copper alloys are banned, such as ammonia lines or certain battery and electronics plants.
The B52- prefix marks a build where copper and copper alloys are not permitted; the exact material substitutions should be confirmed with us. This model includes a CA pivot back cover that swings on a pin for arcing loads, and an -S magnet for use with CMSG (reed) or DMSG/EMSG (electronic) sensor switches. The riveted rolling-packed barrel keeps it light, but it is not designed for disassembly like a tie-rod cylinder.

Where the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL40X150SCA Is Used
Ammonia Refrigeration Valve Actuation
In ammonia-based cooling skids, this copper-free cylinder actuates a 2-way valve stem with 628 N push at 0.5 MPa, where copper alloys would corrode. The 150mm stroke matches the valve travel, and the CA pivot absorbs minor misalignment.
Battery Tab Forming Press
For a lithium-ion tab bending station, this cylinder delivers 880 N push at 0.7 MPa to form a 0.2mm nickel tab. The compact riveted body fits between guide rails, and the -S magnet signals the press controller via a CMSG reed switch.
Electronics Cabinet Door Latch
In a clean-room electronics cabinet, this unit retracts a spring-loaded latch with 528 N pull at 0.5 MPa. The copper-free build prevents ionic contamination, while the CA pivot allows the rod to align with the latch hook without binding.
Is the Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL40X150SCA the Right Cylinder?
For a lighter duty, step down to the MBL32X150 with 402 N push at 0.5 MPa; for more force, the MBL50X150 offers 981 N push at 0.5 MPa. This B52- version is for copper-free environments-confirm the substituted materials with us before ordering. The fixed rubber bumper softens end-of-stroke impact, but it is not a lock; if the load must be held without air pressure, add an external rod lock or pilot-operated check valve.
This SKU has a G1/4 port, 16mm rod with M12x1.25 thread, CA pivot back cover, and PT port thread. The magnet (-S) enables position sensing with CMSG/DMSG/EMSG switches. For side-load resistance at this 150mm stroke, consider an external guide or the MBLD double-rod type.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac B52-MBL Copper-Free Aluminum Alloy Mini Cylinder B52-MBL40X150SCA FAQ
At 0.5 MPa, push is 628 N and pull is 528 N. At 0.7 MPa, push rises to 880 N. The theoretical maximum is 128 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa.
B52- marks AirTAC's copper-free (copper-prohibited) build for lines where copper alloys are banned, such as ammonia systems. The exact material substitutions must be confirmed with us. The base MBL has a fixed rubber bumper that softens end-of-stroke impact-it is not an adjustable air cushion (that is the MBLC variant) and not a lock.
